Your beta 5N works great, but i cannot change the refresh rate to something different than 60Hz.

I prepared special build with new driver. I tested dvb-t and dvb-c successfully. Dvb-s still not working, work in progress to fix dvb-s.

LibreELEC-S905.arm-8.0-devel-7.95.beta5X-20170207093751.img.gz

Pls, test it and let me know

Thanks a lot, DVB-C works like a charm, including oscam!!
sadly, i cannot test DVB-S.
Keep up the good work!

To debug driver from ssh use following commands:

Code

echo 1 > /sys/module/avl6862/parameters/debug_avl
while true; do dmesg -c ; sleep 1; done

this is what i get when tuning to a dvb-c channel. It is the same with VDR and w_scan.

VDR is working again with your new version (2017-02-05), thanks a lot!

dvb-c is not working with VDR, i get the following messages:

Feb 06 12:28:28 k1plus vdr[3748]: [3788] frontend 0/0 timed out while tuning to channel 47 (Disney SD), tp 450

How can i debug this further?

if i understood you correctly, this is now the current version of the linux media_build driver? So the driver is open source now?

I still don't get the device to receive any tv-channel. neither DVB-S nor DVB-T.

you said, that w_scan is not suitable to check, whether the tuner is receiving something, but VDR does not receive anything either!!
i always get the message:
No device provides channel 30 (kabel eins) at priority 0
(this is with stremadev, but local playback in KODI is not working either)

It seems, dvb-t(2) is not working anymore. It did once.

w_scan says:
/dev/dvb/adapter0/frontend0 -> "Availink AVL6862" doesnt support TERRESTRIAL -> SEARCH NEXT ONE.

EDIT:
DVB-S seems not to work either.
/dev/dvb/adapter0/frontend0 -> "Availink AVL6862" doesnt support SATELLITE -> SEARCH NEXT ONE.
/EDIT

Could you re-add the dvb-t capabilities of the tuner?

And thanks a lot for your great work!

Has anyone successfully used the tuner for DVB-C ?

The driver announces dvb-c as available, but i cannot receive anything.
This is also the case, if I use vitmod's image.
